Which Letter
Hear a sound and choose the letter that spells it. Listen to the sound, then tap the matching letter. Play here or use Expand for a distraction-free full-screen activity.
No account is needed. We collect anonymous play events and a masked session recording so we can improve the arcade. Typed inputs are hidden. This activity does not make a reading-level diagnosis. Privacy details.
Embed Which Letter on any static site
The same framework-neutral component works in plain HTML, site builders, and static exports.
